Be it known that I, SAMUEL JQ ZINGMAN,

a Vcitizen of the United States; residing atl New York city, in thecounty of New York 5 and State 0f New York, have invented certain newand useful Improvements in Combination Locks; and I do hereby decla-rethe followingsto be a full,clear, and exact `description of theinvention, such as will 'en- 0 able, others Skilled in the are tewhihitg appertains to make anduse the same;

This invention relates torimpro'vements' `1n combination locks and hasforvone of its oby jects the'p'rovision of a device of this characterwhereby theshackle thereof may be locked and unlocked withouttheuse of'a key Another object of this linvention isfto provide a body adapted toslidablyreceive the `shackle and having a plurality of'lock' ing'elements or tumblers rotatably mounted thereon which may beso'manipul'ated as to lock the shackle in same therefrom.

provide the locking`elements on tumblers with double spaced walls havingslots thereinadapted to 4be alined to permit a portion of the shackle toslide therethrough and which maybe moved to offset cr disaline the.slots thereof to prevent the Withdrawal of the shackle from the body.v

l further Vobject of this invention is the provision of'means formoving'the-fdouble walls in relation to eachother so ,that thecombinationof the device may be readily changed when desired.V

A still further Vob'ect of this invention is theprovision of acombination lock 4of the 40 above stated character, vwhich 's hallbesimple, durable and efficient,- and which may be manufactured and soldat av comparatively lowcost.`

With'these 'and other-objects in view as will becomemore apparent as thedescription proceeds,rthe invention consists in certain novel featuresof construction, combination and arrangement of Iparts' as will'beclaimed.

The clone gatedbody 1fisprovided. with aslot 10 that opens out'through the face thereof toslidably receive the shank 8 and permit'the 55 bits9 tofproject 'beyondthe face thereof for engagementwith ay plurality of locking 'ele-` mentsor \tumblers"11. f

' The lockinggel'eme'nts ortumblers 11 each consists of 'ai p'airofdouble spaced Vwalls v12; 90- each'vvall consistingof plates ordisksv 13and 14. The disksr plates 13 are ofa'greater diameter than theplatesjordisks 1 4 and have mounted upon l`the peripheriesjthereof a band'i'on'.which is` applied various 95 characters for'thepurpose of aiding insolving fthe' combinationl of fthe #dev i'cew The disks or plates' 13and 14: are-eachvprovided with` circularopenin'gs'to'receive the body 1so *they 'can rotate freely thereon. The 100 `plates or disks 13 of eachof the locking elements or tumblers 11 are provided withy a yatransversel sectional view clearlyshown in Figure 2. f

The plates or disks 13 are each providec with a substantially circulargroove orslot' 17 A that extends substantially about said disks orplates 13 and slidably receives pins 18 formed upon the plates 14. Thepins18 have formed thereon heads 19 that riction` ally engage the outerfaces of the plates 13` to prevent accidental movement of the plates 14:inrelation to the plates 13, When'the device is in use.

ln assembling the device, the sectionsfland 5v of the shackle 3 aremoved apart so that the loc-king elements orv tumblers 11 may be readilyinserted upon the body inv clos-eproximity to each other. The locking'elements or tumblersare( held upon the body 1 by means ot a springactuated pin or plunger 18 carried by the body so that they cannotbecome detached from the body when the lock is open.y To lock thedevice, the sections It `and 5 of'theshackle 3 are movedv`v inthedirection of each otherA causingthe shank 8 to move within"y the slot1() of the bodyA and the bits9 to pass through the alining slots 1.5 and16 of the plates 13 and 14 to position themselves between'thewalls of?the locking elements ortumblersll.A The locking' elements or tumblers 11arel then ro,

tated about the body 1 so asfto disaline the slots of the plates 13 and14 fromregistering with the bits 9 thereby preventing` the shackle 3k,from being` opened.v When the shackle 3 is in a locked or closedposition as illustrated in Figures 1` and 2, the end yclosure plate 7 isin closeproximity to the locking' elements `or tumblers 1-1 so that itis impossible to actuate` lthe spring plunger to disarrang'e or removethem rom'the body. To unlock the device, the locking;` elements ortumblers 11 are rotated onv thel body 1 so as to aline the slots in theplates113 and 14 with the bits 9 and thesectionse and 5 of the shacklemay then be readily separated so as to disengagje thefshank 8 from thebody 1.

- 1n order to changel the combination of the locking elements ortumblers 11, they are removed frointhe body 1 by pressing` invvard` lylupon the pin 18 and the plate-s 14 are of the shackle and having agroove opening out through the face and one end thereof, a shank formedon the other section of the shackle, bitsr formed on said shank and eX-tending beyond the face of the body, spaced pairs of disks rotatablymounted on the body y and each having a plurality of slots' to receivethe bits, bands secured to the periph` eries oi the disks, and a secondIdisk for each4 one of each pair of disks, said lsecond disks mounted on"the body between the first' named pairs of disks andeach having a slotthe slots ofthe rstfnamed disks.v 'y 2.
